OpenAI Membina Platform Kod Sendiri untuk Menggantikan GitHub: Pemisahan Microsoft Semakin Pantas

The news leaked on March 3, 2026 via The Information, quickly picked up by Reuters: OpenAI engineers are working on a code repository management tool that could replace GitHub. The official trigger? Repeated outages on Microsoft's platform that seriously disrupted internal development workflows. But behind this technical pretext lies a far more explosive strategic message.

Repeated GitHub outages: the technical trigger

GitHub is the central nervous system of virtually every development team in the world. When the platform goes down, it's not just a few files becoming inaccessible — entire CI/CD pipelines stop, deployments fail, code reviews fall behind. For a company like OpenAI, iterating at breakneck speed on its AI models, every hour of downtime is costly.

Recurring GitHub incidents are not a new phenomenon. The platform experienced several major outages between late 2025 and early 2026, causing disruptions ranging from a few hours to a full day on certain services (Actions, Codespaces, API). For most companies, it's an inconvenience. For OpenAI, in the midst of a frantic innovation race, it became an unacceptable operational risk.

The decision to build an in-house alternative is therefore, on the surface, perfectly rational. But it could have been limited to an internal Git mirror, a backup, standard redundancy. Except that's not what OpenAI is doing: the company is building a full-featured repository management tool. And that's where the strategic dimension comes into play.

OpenAI vs Microsoft: an alliance cracking apart

To understand the significance of this decision, you need to trace the arc of a relationship that has grown considerably strained in recent months. Microsoft holds 27% of OpenAI and retains an exclusive license on its intellectual property until 2032. For a long time, the two companies formed a symbiotic duo: money and Azure infrastructure on one side, revolutionary GPT models on the other.

But the close alliance has morphed into a wary coexistence. In mid-2025, the Wall Street Journal revealed that OpenAI executives had seriously considered accusing Microsoft of anticompetitive practices. The accusation was never formalized, but the mere fact that it was discussed internally speaks volumes about the state of the relationship.

“The OpenAI-Microsoft relationship has shifted from a 'strategic partnership' model to a 'coexistence under tension' model. Every technical decision is now read through a geopolitical lens.”

In October 2025, both parties renegotiated their foundational agreement. The result: the removal of cloud exclusivity that had tied OpenAI to Azure. In practical terms, OpenAI can now diversify its infrastructure providers to [AWS](https://aws.amazon.com), Oracle, and others. A change that would have been unthinkable two years earlier.

Windsurf, Copilot, cloud: the fronts of the cold war

The Windsurf affair perfectly crystallizes the tensions. When OpenAI acquired this startup specializing in AI-assisted coding, a thorny question immediately arose: could Microsoft, by virtue of its license on OpenAI's intellectual property, claim Windsurf's technology to feed [GitHub Copilot](https://github.com/features/copilot)?

OpenAI said no. Firmly. Sam Altman's company refuses to let its technology — whether developed internally or acquired — be used to strengthen a competing product. Because that's exactly what this is about: GitHub Copilot and OpenAI's future coding tools are in direct competition.

And on the other side of the ring, Microsoft is also preparing its countermove. In mid-February 2026, Mustafa Suleyman, head of Microsoft AI and DeepMind co-founder, confirmed that the company was working on its own foundation models. The stated goal: reducing Microsoft's dependency on OpenAI. The symmetry is striking — each is trying to emancipate from the other.

What OpenAI is actually building

OpenAI's code platform project is still in its infancy. No firm timeline has leaked, and several fundamental questions remain open:

• Internal use or commercial product? Teams are considering offering it to OpenAI customers, but nothing is decided.
• What feature scope? Simple Git hosting, or a complete ecosystem with CI/CD, code review, project management?
• What AI integration? OpenAI's natural competitive advantage would be natively embedding GPT into the developer experience.
• What business model? Open source, freemium, or reserved for API customers?

If OpenAI does decide to commercialize this platform, it would enter direct competition not only with GitHub, but also with [GitLab](https://gitlab.com), Bitbucket, and self-hosted solutions. A mature market, dominated by GitHub and its 100 million developers. The bet would be bold, but OpenAI has an asset no one else possesses: the ability to integrate the most advanced AI on the market directly into development workflows.

What does this mean for developers?

In the short term, nothing changes. OpenAI's project is embryonic and GitHub remains the dominant platform. But in the medium term, several scenarios emerge:

Scenario 1: The tool stays internal. OpenAI uses it for its own needs, the project never ships. Impact for developers: none. But the signal sent to Microsoft remains powerful.

Scenario 2: Launch of a competing product. OpenAI offers an AI-enhanced code platform to companies already using its APIs. The market fragments further, but competition forces GitHub to innovate faster. Developers win.

Scenario 3: Absorption into a larger ecosystem. The code platform becomes a brick in an integrated development environment (IDE + hosting + AI + deployment), creating a lock-in comparable to what Microsoft has built with VS Code + GitHub + Copilot + Azure.

Toward a post-Microsoft AI ecosystem?

OpenAI's decision to build its own code platform fits into a broader movement of de-Microsoftification. Cloud diversification to AWS and Oracle. Acquiring Windsurf to avoid depending on Copilot. And now, an alternative to GitHub. Piece by piece, OpenAI is dismantling the dependency architecture that tied it to its main investor.

This dynamic isn't unique to OpenAI. It reflects a structural trend in the AI industry: companies building the most advanced models also want to control the infrastructure around them. Google did it with its own TPUs and cloud. Meta did it with its own GPUs and open-source infrastructure. OpenAI is following the same path, a few years behind.

The open question is one of timing. Can OpenAI simultaneously pursue the foundation model race (GPT-5, AI agents), API commercialization, acquisition integration (Windsurf), AND building a code platform? Despite its tens of billions in valuation, the company doesn't have infinite resources. Every new front opened is a front that dilutes focus.

One thing is certain: the OpenAI-Microsoft couple, once presented as the most powerful alliance in the tech industry, is transforming into one of its most fascinating rivalries. And for developers, companies, and AI tool users, this competition promises to accelerate innovation like never before.
